Problems solved by technology

This solution requires high precision in the positioning of the drawing-in unit and tensioning unit, for example on rails or flat steel plates, which is correspondingly expensive and leads to less flexibility

Embodiment Construction

[0032] figure 1 A schematic diagram of the principle of the tensioning device S at the tensioning frame R according to the invention is shown. The tensioning device comprises a first support element S-10 which is displaceable along a guide rail FS by means of two guide elements S-11 and S-11'. The first support element S- 10 is embodied here in the form of a support frame, in the plane of which the adjustment mechanism S- 30 for displacing the tensioning unit S- 40 is held. As shown here, the adjustment mechanism S- 30 can, for example, comprise a shaft drive, by means of which the tensioning unit S- 40 can be displaced forwards and backwards in the plane of the carrier frame. Depending on performance and costs, it is of course also conceivable to select another suitable drive, for example a rack or belt drive or other drives known to those skilled in the art. The tensioning unit S- 40 is here fixedly connected to the second support element S- 20 , which is likewise displace...

Abstract

The invention relates to a tensioning device (S) for the warp threads (KF) of a warp thread layer (KFS) with two support elements (S-10, S-20), the two support elements (S-10, The distance between the S-20) can be changed by the adjustment mechanism (S-30) connecting them, and the two supporting elements (S-10, S-20) are connected to the guiding elements (S-11, S) -11', S-21) are connected by means of which guide elements (S-11, S-11', S-21) the support elements (S-10, S-20) can be releasably connected to the common guide rail (FS) is connected and movable along this guide rail (FS), wherein one of the support elements (S-20) carries a tensioning unit (S-40) for re-tensioning at least one warp thread (KF), and supports The elements (S-10, S-20) are provided with stop elements (S-12, S-22) for alternately fixing the support elements (S-10, S-20) at the guide rails (FS) such that The tensioning unit (S-40) can be moved along the guide rail (FS) by means of the adjustment mechanism (S-30). Furthermore, the present invention relates to an assembly formed by a tensioning device (S) and a tensioning frame (R), a drawing-in device comprising the tensioning device (S) and a method for re-tensioning the warp threads of a layer of warp threads.

Description

technical field [0001] The invention relates to the field of weaving technology (Webereitechnik) and in particular to a tensioning device (Spannvorrichtung) for retensioning (Nachspannen) warp threads (Kettfadenschicht) of a warp layer (Kettfadenschicht), by which tensioning device and a tensioning frame (Spannrahmen) formed assembly (Kombination), including a threading device (Einziehvorrichtung) of a tensioning device, and a method for retensioning the warp threads of a warp thread layer. Background technique [0002] Before fabrics (Gebe) or fabrics (Stoff) can be produced by joining warp threads and weft threads on a loom, the warp threads must be threaded (einziehen) into the manufacturing heald frames (Webgeschirr) in a certain order. Generally, heald frames (Webschaft), healds (Weblitze), warp sheets (Kettfadenwächterlamelle) and reeds (Webblatt) are among the components for manufacturing heald frames. Draw-in means that each individual warp thread (which is usually ...
